ENPEP-BALANCE is a nonlinear equilibrium model that matches the demand for energy with available resources and technologies. Its market-based simulation approach allows ENPEP-BALANCE to determine the response of various segments of the energy system to changes in energy prices and demand levels. The model relies on a decentralized decision-making process in the energy sector and can be calibrated to the different preferences of energy users and suppliers. Basic input parameters include information on the energy system structure, base-year energy statistics including production, consumption levels, prices, projected energy demand growth, and any technical and policy constraints.

Approach

ENPEP-BALANCE's graphical user interface allows users to "drag and drop" to build an energy supply and demand network. The model then employs a market share algorithm to estimate the penetration of supply alternatives. It uses an equilibrium solution to develop an energy system configuration that balances the conflicting demands, objectives, and market forces of the economy. 'The ENPEP-BALANCE approach simulates more accurately the more complex market behavior of multiple decision makers that may not be captured by optimization techniques that assume a single decision maker.'

Key Outputs

The equilibrium prices and quantities of energy sources that clear all markets for all energy supply forms and all energy uses included in the energy network. This is an energy system configuration that balances the conflicting demands, objectives, and market forces of the economy. Concurrently with the energy estimates, it computes the environmental residuals associated with a given energy system configuration, including greenhouse gases, criteria air pollutants, waste generation, water pollution, and land use.

The Energy and Power Evaluation Program (ENPEP) is an energy analysis software tool which was developed at Argonne National Laboratory."The Windows version of the Energy and Power Evaluation Program (ENPEP-BALANCE) is the premier energy systems analysis software in use in over 80 countries. ENPEP-BALANCE has been developed by CEEESA with support from the U.S. Department of Energy (DOE). ENPEP-BALANCE allows users to evaluate the entire energy system (supply and demand sides) and the environmental implications of different energy strategies. The latest ENPEP-BALANCE version takes full advantage of the Windows operating environment." [1]
